ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 451,610, dated May 5, 1891.

Application filed J 11119 1 90- Serial No. 354,126. (No model.) Patented in Belgium January 27, 1890, No. 89,304, and in Luxemburg January 30, 1890, No.1,245.

To all whom, it may concern:

Be it known that I, MAX VAN GULPEN, a subject of the King of Prussia, residing at Miilheim-on-the-Rhine, Kingdom of Prussia, have invented new and useful Improvements in Cigar- Znnching Machines, (for WhichI have January 30, 1890, No. 13%,) whereof the following is a specification.

In the specification of the cigar-bnnching machine for which the United States Patent No. 422,325, dated February 25, 1890, has been granted to me I have described a machine which works with an apron attached at both extremities to a table, and a movable frame carrying a roller, by which the fillers, being placed in the bight of the apron and wrapped in the latter, are compressed with a rolling action into a bunch. This bunch is enveloped in the binder-and deposited by the apron in an open mold provided with a cover or hinged top part, which compresses the bunch and imparts to it the required form, the closed mold being afterward removed from the machine and taken to the operator who puts on the wrappers.

According to my present invention 1 cmploy in place of single molds, as described in my said former specification, a number of connected molds or a multiple mold so arranged as to be capable of rotating or otherwise traveling with a suitable step-by-step motion in front of thedelivery end of the table of the machine, so as to receive the bunches one after the other, thus obviating the inconvenience attending the previous ar rangement and arising from the necessity for removing each mold separately and putting another into position whenever a bunch is delivered from the table. The said multiple mold is composed of sections forming together a series of divided moldingcavities and so connected side by side to a carrier that they may be shifted in transverse direction relatively to each other. hen these sections are pushed close together and kept in this position, they are in the state for receiving the bunch and allowing the same to be compressed they are spread apart or shifted away from each other they release the molded bunch so that it may then easily be removed.

The carrier to which the sections are connected may consist in a double traveling chain running over two barrels or in a sliding frame or a rotating shaft. In the first arrangement the sections are so fixed or connected to the links of the chain as to be in contact with each other when the chain is stretched out in a straight line, as is the case relatively to the parts of the chain being, during the motion of the chain, between the two barrels, the sections under these conditions spreading apart automatically as the chain passes upon either barrel. In view of securelykeeping the chain straight between the barrels it may be supported by guides. If the carrier is to consist in a sliding frame or a shaft, one or more clamps or key-pieces are provided for, whereby the sections can be kept close together or released at will.

In Figures 1 to 7 of the annexed drawings a multiple-moldingapparatus of my invention is represented, in which the mold-sections are mounted on a shaft so as to form a cylinder. Fig. 1 is an end view showing the counter-mold piece and certain levers turned back. Fig. 2 is a plan corresponding to Fig. 1. Fig. 2 is a sectional viewof a detent mechanism. Fig. shows the apparatus in end view with the counter-mold piece turned down into the uppermost cavity of the mold-cylinder and the said levers in operating position. Fig. & is a transverse section, and Fig. 5 a longitudinal section, of the mold-cylinder. Fig. 6 shows in end elevation and in top view the countermold piece with parts to which it is fixed. Fig. 7 is a perspective view of three sections of the mold-cylinder placed in their proper relative position, except that they are spread far apart, some portions being broken away. Fig. 8 is an elevation of the modified apparatus, in which the mold-sections are attached to chains running over two barrels. Fig. 9 is a transverse sectional view thereof on line 1 2, Fig. 8. Fig. 10 shows in sectional elevation a multiple mold inclosed in a frame that serves as a carrier. Fig. 11 is a partial transverse section, and Fig. 12 a plan of the same.

The said mold-cylinder is composed of a plurality of sections f, forming on each side one-half of a mold, and two sections jf'-, haw

ing the form of a mold-half on one side only.

All these mold-sections are provided with eyes 1', Fig. 7, with which they are strung on the shaft 1/, and they are arranged to have so much play that when they are all pushed close together a space will be left between two of thennsuchasis shown in the drawings between the sections f and f The section f is preferably fixed to the shaft. lly these means all the sections except the section f" are rendered capable of being rocked on the shaft and of being shifted laterally one after the other in view of spreading them apart and allowing the bunches deposited in the molds to be removed.

For the purpose of maintaining the sections fin contactwith each other and with the sectionsff during the operation of molding a wedge-like key-piece q is inserted into the space between the sections ff This keypiece is pivoted to the section f and provided with an arm whereby it may be turned up and down, as shown in Fig.

The described mold-cylinder is placed with its shaft 7U in bearings formed in a frame 0, and which are so constructed as that the cylinder may be easily removed and exchanged for another one.

Opposite to the cylinder is pivoted to the frame 0 a plate t, carrying the COIllltQP-ll'lOld piece If in such position that when the plate is swung toward the cylinder the piece t will engage with the uppermost molding-cavity thereof, (see Fig. 3,) while on the other side of the cylinder are mounted 011 a shaft 9 two lever arms I, provided with handles and adapted to be turned down on the bar t fixed to the plate 23, this arrangement affording 4o convenient means for pressing the piece 1 down upon the bunch present in the said molding-cavity.

In order that previous to each molding operation the molding-cylinder may be arrested 5 in such position that one of its cavities is in the path of the counter-piece 25 when being swung over, a detent mechanism is provided for. This mcchanism,as shown by the drawings, consists in a disk 12, secured to the sectionf, and a conically-pointed retaining-pin p, guided in a sleeve 11 and impelled by means of a spring 1)" against the disk 2), which is furnished. with holes for the pin to engage in, the said holes being so arranged that every time the pin is in engagement with one of them the corresponding molding-cavity will be in the proper position for receiving a bunch as well as the counter-mold piece/'', and the cavity will be kept in this position until the requisite rotativc force is applied to the cylinder to cause the pin to be pushed back.

In the modified arrangement shown by Figs. a and 9 the mold-sections f are fixed to the endless chains to. having pins Z), which ongage with teeth on the barrels or sprocketwhcels c. The mold-sections are guided during the upper part of their course bythe bars (Z. 71. is a detent operating on the teeth of one of the wheels 0.

The second modification (represented by Figs. 10 to 12) also consists in mold-sections attached to chains; but the chain-mold thus produced is inclosed in a frame 75, arranged to be opened at one end and provided with a screw for pressing the sections together.

I claim as my invention 1. For use in a cigar-bunching machine, a multiple bunching-mold composed of the sec tionsff'fi, forming togcthera series of divided molding-cavities, a shaft 11', carrying the said sections, the scctionsfand f having eyes with which they are strung on the said shaft, and the key-piece q, pivoted to one of the sections ff and adapted to be inserted between the said sectionsff in combination with a counter-mold piece f, fitting into the molding-cavities, andnleans whereby the said piece 25 is guided to engage with the cavity brought into the path of the same, substantially as specified.

2. For use in a cigar-bunching machine, a multiple lmnching-m old composed of sections forming together a series of divided moldingcavities, a carrier to which the said sections are connected, so as to be capable of transverse motion relatively to each other, and means for keeping the contiguous sections in contact with each other and fol-allowing them to be spread apart, in combination with a movable counter-mold piece fitting into the molt'ling-cavities, means for guiding the said piece, and a detent mechanism whereby the btmching-mold is arrested whenever one of the molding-cavities has been brought into the path of the counter-mold piece, substantially as set forth.

In testimony whereof I have hcreu n to set my hand in the presence of two subscribing witnesses.
